NON-REFILLABLE BOTTLE.

Specification of Letters Patent.

.tatented Mar. 8, 1921.

Application filed January 24, 1920. Serial No. 353.695.

To all whom it may concern:

Be it known that I, FRANK Sierras, a citizen of Greece, and subject of the King of Greece, residing at Spokane, in Spokane county and State of \Vashington, have invented certain new and useful Improvements in Non-Refillable Bottles, of which the following is a specification.

The present invention relates to an improved non refillable bottle of that type employing a series of outwardly opening valves which permit emptying of the bottle, but efiectually prevent refilling of the same after the contents have once been used.

To this end the invention consists essentially in the utilization of a specially designed sleeve or shell for insertion and retention within the bottle neck containing a multiplicity of outwardly opening, pivoted disk valves, and in the combination and arrangement of these pivoted disk valves with the shell, and in novel formations whereby the outward movement, under normal con ditions, of the valves is regulated, all as will be hereinafter more fully explained and pointed out in the accompanying claim.

in the drawings which I have utilized to exemplify my invention I have illustrated one complete example of the physical embodiment of my invention, constructed and arranged according to the best mode I have so far devised for the practical application of the principles of the invention, and inasmuch as the drawings show an exemplification of the device, it will be understood that changes or alterations may be made within the scope of my claim without departing from the spirit of the invention.

Figure 1 is a vertical central sectional view of a bottle neck and portion of a bottle having the device of my invention embodied therein.

Fig. 2 is a view in section at the upper end of the bottle neck, on line 2-2 of Fig. 1.

Fig. 3 is a transverse sectional view of the bottle neck and device, at line 8-3 of Fig. 2.

In order to illustrate the adaptation of the bottle closure I have indicated in the drawings by the numeral 1, a usual form or type of bottle neck having on its interior walls ribs or lugs 2 and the usual flanged mouth 3.

Vithin the bottle neck is fixed the shell or sleeve 4, preferably made of rubber or similar material, which when heated preparatory to insertion into the bottle neck,

may be introduced therein while in a flexible or plastic state and subsequently hardened to engage at its outer periphery with the lugs or ribs 2 for firmly and securely holding the shell or sleeve against removal from the bottle neck.

The bottle neck is tapered and the exterior and interior walls of the sleeve are also tapered as shown, and the interior of the shell is fashioned to receive a plurality of valve disks 5, 6, and 7, decreasing in diameter from the upper one to the lower one. These disks are made up of resilient mate rial with sufficient elasticity to permit their forcible insertion into the shell to rest upon the respective seats 5 6 7 that are formed by the annular ledges or flanges thus designated on the interior wall of the sleeve.

Each disk valve is equipped with a radial lug 8 of rectan ular formation projecting from the periphery thereof and adapted to fit into a socket 9 therefor in the wall of the shell or sleeve, and between the lug and back wall of the socket a resilient packing member or block 10 is located to form a cushion or filler for the lug to hold the disk in stable position in contact with the interior wall of the sleeve when the valve is closed, and also to maintain the disk valve in uniform relation to the sleeve while the valve is opening or closing on the lug as a pivot in the socket.

On the wall of the shell opposite each lug is fashioned an integral rib to guide the disk valve in its movement, indicated at 11 and projecting from the sidewall toward the center of the shell. Preferably the ribs 11 are staggered as shown in Fig. 1, two of them being located at one side of the interior of the sleeve and the intermediate one being located at the opposite side, the pivots of the disk valves also being arranged in this staggered manner. At the upper end of the curved edge of each rib, a retaining head 12 is fashioned to project beyond the end of the curved guide rib and form a sto for the disk in its swinging or upwardly pivotal movement, thus limiting the opening movement of the valves.

After the shell or sleeve and its valves have been located in proper position the open mouth of the shell and bottle neck are closed by a cap 13 fashioned with a laterally extended nozzle 14, the cap being sealed, as by cement, and forms an effectual means for preventing access to the interior of the shell or tampering with the disk valves. Usually a cork is placed in the open end of the nozzle until the bottle is ready for use. Liquid may be poured through the open end of the nozzle in usual manner, the disk valves, when the bottle is inverted, being moved to the dotted line position in Fig. 1 to permit the passage through the shell of the liquid. WVhen the bottle is again righted, the valves fall by gravity to their seats forming a closure against entrance of any liquid or other material, and in this manner a non-refillable bottle of desirable utility is provided.

Having thus fully described my invention, What I claim as new and desire to secure by Letters Patent is The combination With a tapering bottle rality of disk valves each having a peripheral lug in a recess and adapted to rest upon a seat, said tube having an inwardly pro- -jecting vertically disposed rib opposite each recess With its outer edge curved on the are of a circle struck from said recess as a center to form a guide for a disk valve, and the end of each rib fashioned with a horizontally projecting retaining head to limit the movement of the disk valve.

In testimony whereof I ailix my signature.
